After some website disruption over the last 24 hours, I’m happy to report that the changes are complete. What? You haven’t spotted them?
Well, they’re both in the address bar at the top of your screen. First of all, the domain is now artiss.blog and not artiss.co.uk (this was always a blog rather than a company, so the recent launch of the .blog domain has allowed me to correct this).
Secondly, I now have a sparkly SSL certificate installed, hence the https and padlock at the beginning. Combined with running under PHP 7, my site now meets the latest recommendations for a WordPress site.
